Frimpong's two appearances for Arsene Wenger's team in 2012-13 have both come in the Capital One Cup. He came off the bench in the 6-1 victory over Coventry before starting in the Gunners' topsy-turvy 7-5 win against Reading.

After making 14 appearances in all competitions for Arsenal last season, Frimpong joined Wolves on loan but played only five times before suffering the serious knee injury.

He joins Charlton on the back of their 1-0 victory over Burnley on Saturday. Chris Powell's team currently lie in 14th place in the Championship.
